INVENTOR MERRILL W. WRIGHT BY mz,

ATTORNEY United States Patent 3,172,533 CLOSURE FOR ROLLS OF WIRE NETTING Merrill W. Wright, Auburn, Mass, assignor to G. F. Wright Steel & Wire Company, Worcester, Mass., a corporation of Massachusetts Filed July 16, 1963, Ser. No. 2%,453 6 Claims. (Cl. 20659) Woven wire fabrics such as poultry wire, wire netting and similar fabrics, are customarily produced in substantially endless strips and as produced the strips are wound in coils or courses to form rolls, the strips of fabric being cut across parallel to the axis of the roll in lengths providing the desired amounts to be shipped in each roll. This cutting makes sharp, raw ends of wire. In order to secure the roll for shipment, an operator grasps each cut end of the wire at the trailing end of the roll with a plier and with a twisting motion he forces the cut end into the fabric of the netting and slightly backwards in what might be described as a series of hooks to keep the material from unwinding and also to avoid the raw edges and cut ends of the wire.

Accordingly it is the principal object of this invention to provide means for more quickly and easily securing the trailing end of the roll for shipping purposes and to obviate any damage which may be done by the trailing end without the necessity of having the operator individually grasp each cutting end and twist it under.

To this end this invention provides a device for closing and holding in closed condition the trailing end of a rod of woven wire fabric, and this device resides in the provision of a relatively simple and easily applied member for covering the cut end of the roll, and binding or otherwise securing the cut end to the adjacent coils or courses of the roll.

Another object of the invention resides in the provision of a device which may be merely pressed into the roll of woven wire fabric at or along the line of the cut wires at the trailing end, covering the same and quickly and easily attaching the trailing end of the roll to the other coils of the roll, and comprising an elongated member having substantially the length of the roll and provided with projections which easily enter the interstices of the wire fabric and become lodged therein due to serration-like shoulders on the heads, thus securing the trailing end of the roll to the rest of the roll. This member can easily be manually stripped off the roll to open the roll when it is to be used.

The invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly set forth in the appended claims.

Reference is to be had to the accompanying drawings, in which:

FIG. 1 is an elevational view with part cut away and in section showing the device to be applied to a roll of wire;

FIG. 2 is an end view, looking in the direction of arrow 2 in FIG. 1, with part cut away;

FIG. 3 is a plan view showing the device applied to a roll;

FIG. 4 is a diagrammatic view illustrating the action of one of the locking devices;

FIGS. 5 and 6 are views similar to FIG. 2 showing modifications, and

FIG. 7 is a section on line 7-7 of FIG. 6.

In carrying out the present invention there is provided a generally flat elongated strip of a suitable material as indicated at 10. Metal or plastic or even wood could be used for this purpose. This strip may have angled edges 12 if desired. Extending from one flat face of the strip there are provided a plurality of arrowhead-like members 14 each of which is provided with a series of reversed notches 16 at the edges thereof. These notches provide locking shoulders 18.

The members 14 can be struck down from the strip 10 leaving openings 20, and members 14 can be arranged at any desired orientation relative to the strip. As shown in FIG. 5, arrowheads 22 with but a pair of shoulders 24 can be used, or double heads 26 with four shoulders 28 as in FIGS. 6 and 7 can be used, and various other forms of arrowheads may of course be utilized.

When the roll of wire 30 is ready for closing, the operator merely takes the flat base member 10 and thrusts it with-the pointed ends of the arrowheads down through the meshes or interstices of the roll of wire, covering at least in large part the cut ends along line 32. The arrowheads penetrate the first several layers of the wire and the shoulders 13 snap under certain of the wires, thus securing the base member 10 on top of the trailing end of the wire as shown in FIG. 1. This not only holds the entire roll closed, but also conceals the cut ends of the wires. At the same time it will be seen that it is a relatively easy matter to manually strip the closure member as described from the roll when it is desired to open the same.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. In a roll of wire netting including a continuous strip wound on itself in a plurality of courses, said strip having a trailing end at the outer surface of the roll and said trailing end including raw edges of wire, a closure for the roll comprising a member overlying the trailing end of the strip and the raw edges thereof, said member extending substantially the length of the trailing end, and integral means on the member penetrating certain courses of the strip adjacent the trailing end, said means engaging portions of the wire in the penetrated courses and holding the member to the roll with the trailing end of the roll between the member and the remainder of the roll.

2. A closure for a roll of wire netting wherein the roll includes an elongated strip of netting wound upon itself in a plurality of courses and having a terminal end at the surface of the roll with the terminal end having an edge that extends from end-to-end of the roll, said closure comprising a member extending in general parallelism to the terminal end edge and overlying and protecting it, said member extending substantially the length of the roll, an element on the member penetrating at least one course of the roll under the terminal end edge, and integral means on the element engaging a portion of the wire forming a part of the course penetrated, said means holding the closure member in its roll closing position.

3. The closure of claim 2 wherein said element includes shouldered arrow-like points, the shoulders thereof being adapted to extend under certain of the wires in the wire roll securing the trailing end of the roll to other portions thereof.

4. The device of claim 2 wherein the terminal end edge has cut wire ends.

5. The closure of claim 2 wherein said element includes shouldered arrow-like points, the shoulders thereof being adapted to extend under certain of the Wires in the wire roll securing the trailing end of the roll to other portions thereof, said arrow-like points each having a plurality of shoulders thereon.

6. The closure of claim 2 wherein said element includes shouldered arrow-like points, the shoulders thereof being adapted to extend under certain of the Wires in the wire roll securing the trailing end of the roll to other portions thereof, wherein said arrow-like points have serrated edges presenting more than a single pair of Wire retaining shoulders. 7
